CLASS 1: This is a low-level outbreak, usually in a Third World country or First World rural area. The number of zombies in this class of outbreak ranges between one and twenty. Total human casualties (including those infected) range from one to fifty. The total duration, from the fist case to the last (known), will range between twenty-four hours and fourteen days. The infested area will be small, no larger than a twenty mile radius. In many cases, natural boundaries will determine its limits. Response will he light, either exclusively civilian or with some additional help from local law enforcement. Media coverage will be light, if present at all. If the media is present, look for common stories like homicides or "accidents." This is the most common type of outbreak and also the easiest to go unnoticed.CLASS 2: Urban or densely populated mral areas are included in this level of outbreak. Total zombies will range between twenty and one hundred. Total human casualties may reach as high as several hundred. The duration of a Class 2 attack may last no longer than a Class 1 outbreak. In some cases, the larger number of zombies will spark a more immediate response. A rural, sparsely populated outbreak may extend to a hundred-mile radius, while an urban outbreak may encompass only several blocks. Suppression will almost certainly be organized. Bands of civilians will be replaced by law enforcement. Look for an additional, if low-level, military response, the TA in the UK or its equivalent abroad. Most often, so as to ease panic, these units will take a more non-combatant role, providing medical assistance, crowd control, and logistical support. Class 2 outbreaks almost always attract the press. Unless the attack occurs in a truly isolated area of the world, or one where the media is strictly controlled, the story will be reported. This does not mean, however, that it will be reported accurately.CLASS 3: A hue crisis. Class 3 outbreaks, more than any other, demonstrate the clear threat posed by the living dead. Zombies will number in the thousands, encompassing an area of several hundred miles. The duration of the attack and a possible lengthy mop-up process could last as long as several months. There will be no chance for a press blackout or cover-up. Even without media attention, the sheer magnitude of the attack will leave too many eyewitnesses. This is a full-blown battle, with law enforcement replaced by units of the regular military. A state of emergency will be declared for the infested zone, as well as the neighbouring areas. Expect martial law, restricted travel, rationed supplies, federalized services, and strictly monitored communication. All these measures, however, will take time to implement. The initial phase will be one of chaos as those in power come to grips with the crisis. Riots, looting, and widespread panic will add to their difficulties, further delaying an effective response. While this is happening, those living within theinfested area will be at the mercy of the undead. Isolated, abandoned, and surrounded by ghouls, they will have only themselves to depend on.CLASS 4: An undead world
